Shore is an integration of file system and OODB concepts and services. From the file system world, Shore draws object naming services, support for lower (and cheaper) degrees of transaction-related services, and an object access mechanism for use by legacy Unix file-based tools. From the OODB world, Shore draws data modeling features and support for associative access and performance acceleration features. To provide scalability and a basis for parallelizing the system, Shore also employs a novel architecture, including support for symmetric peer-to-peer server communication and caching; in addition, it includes support for extensibility via the value-added server facility. Like our previous system, EXODUS, we will make the Shore system publicly available via anonymous FTP; we expect the first release of Shore to occur in mid-1994.
